9f2ec3f543 spl: consolidate arch/arm/include/asm/arch-*/spl.h
arch/arm/include/asm/spl.h requires all SoCs to have
arch/arm/include/asm/arch-*/spl.h.

But many of them just define BOOT_DEVICE_* macros.

Those macros are used in the "switch (boot_device) { ... }"
statement in common/spl/spl.c.

So they should not be archtecture specific, but be described as
a simpile enumeration.

This commit merges most of arch/arm/include/asm/arch-*/spl.h
into arch/arm/include/asm/spl.h.

With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h
will be merged, while I am not sure about OMAP and Exynos.

a0a37183bd ARM: omap: merge GPMC initialization code for all platform
GPMC controller on TI's OMAP SoC is general purpose controller to interface
with different types of external devices like;
 - parallel NOR flash
 - parallel NAND flash
 - OneNand flash
 - SDR RAM
 - Ethernet Devices like LAN9220

Though GPMC configurations may be different for each platform depending on
clock-frequency and external device interfacing with controller. But
initialization sequence remains common across all platfoms.

Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c
files into single omap-common/mem-common.c

However, actual platforms specific register config values are still sourced
from corresponding platform specific headers like;
 AM33xx: arch/arm/include/asm/arch-am33xx/mem.h
 OMAP3:  arch/arm/include/asm/arch-omap3/mem.h
 OMAP4:  arch/arm/include/asm/arch-omap4/mem.h
 OMAP4:  arch/arm/include/asm/arch-omap5/mem.h

Also, CONFIG_xx passed by board-profile decide config for which set of macros
need to be used for initialization
 CONFIG_NAND:    initialize GPMC for NAND device
 CONFIG_NOR:     initialize GPMC for NOR device
 CONFIG_ONENAND: initialize GPMC for ONENAND device

ps7_init.c and ps7_init.h are supposed to be exported by hw project

We want them to be ignored by git.
So what we should do is to always treat them as external files
rather than replacing ps7_init.c

This commit does:

 - Move a weak function ps7_init() to arch/arm/cpu/armv7/zynq/spl.c
   and delete board/xilinx/zynq/ps7_init.c

 - Compile board/xilinx/zynq/ps7_init.c only when it exists

2364e151e4 ARM: tegra: use a CPU freq that all SKUs can support
U-Boot on Tegra30 currently selects a main CPU frequency that cannot be
supported at all on some SKUs, and needs higher VDD_CPU/VDD_CORE values
on some others. This can result in unreliable operation of the main CPUs.

Resolve this by switching to a CPU frequency that can be supported by any
SKU. According to the following link, the maximum supported CPU frequency
of the slowest Tegra30 SKU is 600MHz:

repo http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=summary
branch l4t/l4t-r16-r2
path arch/arm/mach-tegra/tegra3_dvfs.c
table cpu_dvfs_table[]

According to that same table, the minimum VDD_CPU required to operate at
that frequency across all SKUs is 1.007V. Given the adjustment resolution
of the TPS65911 PMIC that's used on all Tegra30-based boards we support,
we'll end up using 1.0125V instead.

At that VDD_CPU, tegra3_get_core_floor_mv() in that same file dictates
that VDD_CORE must be at least 1.2V on all SKUs. According to
tegra_core_speedo_mv() (in tegra3_speedo.c in the same source tree),
that voltage is safe for all SKUs.

An alternative would be to port much of the code from tegra3_dvfs.c and
tegra3_speedo.c in the kernel tree mentioned above. That's more work
than I want to take on right now.

While all the currently supported boards use the same regulator chip for
VDD_CPU, different types of regulators are used for VDD_CORE. Hence, we
add some small conditional code to select how VDD_CORE is programmed. If
this becomes more complex in the future as new boards are added, or we
end up adding code to detect the SoC SKU and dynamically determine the
allowed frequency and required voltages, we should probably make this a
runtime call into a function provided by the board file and/or relevant
PMIC driver.

bb14469ae0 ARM: tegra: add function to enable input clamping on tristate
The HW-defined procedure for booting Tegra requires that
CLAMP_INPUTS_WHEN_TRISTATED be enabled before programming the pinmux.
Add a function to the pinmux driver to allow boards to do this.

4a68d3431a ARM: tegra: allow pinmux mux option not to be set by init tables
Define enum PMUX_FUNC_DEFAULT, which indicates that a table entry passed
to pinmux_config_pingrp()/pinmux_config_pingrp_table() shouldn't change
the mux option in HW.

For pins that will be used as GPIOs, the mux option is irrelevant, so we
simply don't want to define any mux option in the pinmux initialization
table.

The register writes performed by arch/arm/cpu/arm720t/tegra30/cpu.c
enable_cpu_power_rail() set the voltage to 1.0V not 1.4V as the comment
implies. Fix the comment.

f6ae1ca058 S5P: Exynos: Add GPIO pin numbering and rename definitions
This patch includes following changes :
* Adds gpio pin numbering support for EXYNOS SOCs.
  To have consistent 0..n-1 GPIO numbering the banks are divided
  into different parts where ever they have holes in them.

* Rename GPIO definitions from GPIO_... to S5P_GPIO_...
  These changes were done to enable cmd_gpio for EXYNOS and
  cmd_gpio has GPIO_INPUT same as s5p_gpio driver and hence
  getting a error during compilation.

* Adds support for name to gpio conversion in s5p_gpio to enable
  gpio command EXYNOS SoCs. Function has been added to asm/gpio.h
  to decode the input gpio name to gpio number.
  Example: SMDK5420 # gpio set gpa00
